To all whom it may concern.:

Be it known that I, EDWARD DUMMER, a citizen of the United States, residing at Auburndale, in the city of Newton, county of Middlesex, and State of Massachusetts, have invented a new and useful Improvement in Supports for Spindles and Rings of Ring Spinning and Twisting Machines, of which the following is a specification, reference being had to the accompanying drawings.

In ring-spinning frames the spindles are now commonly more or less flexibly supported, so that they, when carrying an unbalanced load, may gyrate, or so that any vibration arising therefrom will not be communicated to the frame. A spindle thus supported may be of much less weight to carry the required load and may be run by means of less power than one for which there is no such provision, since t-he spindle and load may revolve about their center of gravity, or nearly so, rather than about their geometrical center, when these centers do not coincide. Any forcesuch as results from the pull of the threadwhich tends to move the spindle out of such' center of rotation necessitates greater weight in the spindle and more power to drive it than if 'such force did not exist.

Vhile many different devices have been employed whereby the spindle may have the lateral motion of gyration or vibration, the ring has heretoforebeen, so far as relates te lateral motion, rigidly xed in the frame. In practice the thread, by which there is a draft largely between and in like degree on the spindle and the ring, acts to pull the spindle out of its proper center of rotation. In all ring-spinning this pull is considerable, so that the bolster must be much more firmly held than otherwise might be. For much ringspinning and in all ring-twisters the bolster must be practically so rigidly held that the spindle cannot gyrate or vibrate, as desired. Furthermore, lall gyratory or vibratory motion of t-he spindle, owing to whatever cause, results,-of course, in a constant or intermittent eccentricity of the spindle with reference to the xed ring, which is very undesirable for many obvious reasons.

.My invention has two main objectse-lirst,

Y to prevent that draft of the thread which is on both spindle and ring from pulling the spindle out of its proper center of rotation, and, second, to maintain the spindle in the center of the ring, the general result being that the spindle may have a much greater freedom inA its gyratory or vibratory movement, and therefore will run much easier th an heretofore, and also that the draft on the thread may be at all times the same, and the thread will not be sub j ected to unequal strain or sudden jerks to an ex'tent not before attained.

The invention consists in so combining the spindle with the ring for operation in the machine that the ring may have a lateral metion corresponding to that of the spindle, and

that the pull by the thread on the ring may Y be caused to balance or counteract the pull on the spindle, as hereinafter set forth, and specifically pointed ont in the claims. i

In the drawings, (two sheets,) Figure l shows an elevation, partly in section, of so much of a spindle, bolster, and support therefor, a ring, and means for connecting the ring with the spindle and operating the ring as is sufficient to illustrate a device embodying my invention. Fig. 2 is a plan of the support or stand F. Fig. 3 is a plan of the bolster, arms b, and bearings c. Fig. 4 is a transverse central section of stand F. Fig. 5 is a transverse central section of the bolster, an arm, l), and a bearing, c. Figs. G, 7, 8, 9, and 10 illustrate modifications to adapt the invention to certain classes of spindle bearings and supports or to differently-consti?ucted machines.

The spindle A, whirl B, hobhin C, and ring D shown are each of a well-known form and construction. Referring, first, to Fig. l and illustrations of details thereof fixed to the bolster a, which may also be like those in commen. use and located as required with reference to the whirl, are shown two arms, b, to each of which is fixed a bearing, c, in which may slide a rod, E, parallel or longitudinal with the spindle. To the upper ends of these rods is fastened the ring D. The stand or support F may be adjusted and fixed on the usual rail, G, in the common manner by means of the threaded stud d and nut c. -It has a vertical projection, 1, thereon, with which the bolster e is pliahly or iiexibly connected. This may be effected by means of a packing, g, formed of any material known for like purpose.. This connection may be suoli that the bolster uand arms A71 may be suspended thereby, there being shoulders o. and j" on the exterior of the bolster and interior of projection f, as shown. The ringI D, and hence rods E, are fiexibly connected with a rail, Il', which rail corresponds to the common ring-rail, and is to have a. like vertical move nient. 'lhis connect-ion may be. made by means of two spiral springs, 71, each fastened at one end on a stud, V1', on an arm, i', applied or fastened to a rod, E, and at the other end on a stud, j, on an armj, applied or tastened to the rail ll. The step t'l for the spindle may be a removable piece set in the base of'l the stand or support lf.

I have made such provision that the bearings for the spindle and also for the slidingl rods E maybe in a chamber for oil. Project.` ingl downward trom the stand or support F are two tubes, closed at the bottom, open at the top, and extending downward suttieiently to allow the rods E to enter therein the required distance. On the base of the stand or support F is secured a removable cap, l, as by means ot screws fm, there being some materia-l, n/-such as leather-in a groove, n, in the base and between the base and Cap. This Lcap has two tubular projections, o, to inclose the bearings c, and a tubular projection, p, to inelose the bolster u, these projections bein of sufficient height to keep the bearin well oiled and of sufficient interior capacity to allow the lateral motion ot' the inclosed bearings.

The operation is simple. An unbalanced load on the spindle will cause thelatter when revolved to gyrate. The bolster o., arms b, bearings c, rods E, and ring l') will have a corresponding lateral mot-ion, while the ring is moved up and down as required to build the thread on the bobbin, the rods sliding in their bearings hence the spindle, having' been set with reference to the ring in the construction ot the device so thattheir centers coincide, will always be in the center' of? the rin rlhe pull by the thread. u, so f'ar as it is alike in degree on the ring (by means ot' the usual traveler shown) and on the spindle, will have no etect on the gyratory motion, or to move the spindle out ot its proper center ot' rotation, since the pull on the ring will, tln'ough the ring, bolster, and the connecting parts, act counter to thepull directly on the spindle.

It is true that the weight oli' the ring and parts connecting the same with the bolster add to the weight heretofore gyrated; but it is found that such additional weight is a restraint on the gyration in a far less degree than that hereto'f'ore required to Overcome the pull ot' the thread and obtained by makingl the connection between the bolster and fixed support more or less rigid. ln f'aet, while top or balanced spindles connnon terms for spindles which may gyrate-arenot practicable in. twist;ingii'a.mes in which the pull of the thread great, and only to a eern tain extent in spinning-frames, my device not only may be employed onv either, butthe connection between the bearing ot the spindle and the fixed support may be very fiexilile and allow an exceedingly tree movement. So very fiexible or yielding `may such conne@ tion be that i fi' the packing o is not desired it may be dispensed with, as hereinafter shown.

lfig. t shows a modified construction in which the step for the spindle is fixed to or within the piece forming` the bolster, which is typical ol a certain class ofi' spindle-supports. The bearings tor the rods are connected with the bolster by means ot' a tube, q, which is fixed to the bolster attheupperend. 'lhus the spindle may run in oil, while the bearings for the rods E are not surrount'led by oil. It is not .so necessary that the bearings f'or the rods be in oil, -snce their slow movement causes but little it'riction (jompared with that ot' the rapidly-rta'olving spindle.

Fig. 7 shows how my invtmtion may be adapted to another cla-ss ol'l spin(lle-supports, by means o f' which the spindle may vibrate, or, perhapsmore 11n'operly,by means of which the vibration caused by the spindle when carryin an unbalanced load is prevented from being` communicated to the supporting` rail. Elastic or flexible material, J, is placed between the support and the rail. \Vith such construction l fix the arms l) directly to such support, so that the ring vibrates with the spindle. lhus the centers of the spindle and ringI will always coincide and the pull ot' the thread will react on the spindle, as above set forth.

rllhe leading distinctive featilre of.' my invention is the intel-position of" a connecting medium between a ring and the yielding or tlexil)ly-sumini-tml bolster ot the appropriate spindle, so that when the bolster has a lateral motion bolster and ringl will move laterally as one; and, since this my invent ion is a radical deWirture lrom what has heretofore been known, l do not wish to have it limited by details of? construction in sueh a manner as to lose the spirit thereof.

The invention is applicable to any ot the devices providing for gyration or vibration of? the spindle. There may be many modifications whieh might occur to those skilled in mamitacturing or operating spindles. There may be on ly one arm h and rod E. (Illustrated by dispensing with one arm l) and rod E of Fig. l.) 'lhe lowerendsotl .rods E maybe connected with a vertieally-moving rail, H', below therail (if, as illustrated by Figs. t) and lo, instead of? to a rail, ll, located above the rail G, as in Fig. l. This may be the construction, when, the rods are not inclosed by the oil-i.'eceptaeles, as 'in Fig. l. Other means than the springs 7l off lFig. l. maybe employed for flexibly connecting lthe sliding rods with the rail, as links 7i? (illustrated by Fig. Si) or pliant wires h3, asin Fig. lf?. The bolster' may extend downward as one piece or a rod and` have the arms or medium connecting` with the l OO lIO

ring slide thereon, as illustrated by Fig.' 8, in which the moving rail H is below the spindle-rail, and the arms b', to which the `rods E are fixed, are adapted to' slide on a rod,r, joined to the bolster. llvith such construction the spring h or flexible connection with the movable rail may be central, as shown. This flexible connection with the moving rail may serve` to maintain the spindle in a vertimanufactured and made ready for transportation and use as a complete article comprising both the ring and spindle support, which article may be readily and easily applied to the frame when set up in the factory where it is to be operated, certain work and care which has heretofore been required to fit and adjust the ring on the frame, and the spindlesupport with reference to the ring, being dispensed with.

I claim as my inventionl. The combination, with a spindle, a spindlebolster, and means for supporting said bolster in a yielding or fiexible manner, of a ring, 'and connections between said bolster 'an d ring, whereby the ringis caused to gyra-te or vibrate with the bolster and spindle, substantially as specified.
